To find the proportion that gives the distance between the penguins and the fish tanks (x) based on the distances from the whales to the sharks (30) and the penguins (54) to the fish tanks (45), we need to set up a proportion using the known distances.
The correct setup would be:
\(\frac{30}{54} = \frac{x}{45}\)
This corresponds to the option: 30 over 54 is equal to x over 45
Thus, the answer is:
30 over 54 is equal to x over 45.
